中国脑机接口研究发展及现状——基于中国期刊全文数据库的文献计量分析

Situation and progress of brain computer interfaces in China-a bibliometric analysis of the literature from China national knowledge infrastructure database

目的用文献计量学方法评价我国脑机接口技术的发展现状。方法检索中国期刊全文数据库（CNKI）数据库建库至2013年10月31日出版的脑机接口相关文献，采用多种文献分析软件，从时间分布、学科分布、基金支持、作者、机构、收录期刊及关键词情况等方面分析我国脑机接口技术的发展现状。结果共检出文献877篇，纳入425篇，发表于160种期刊。2002年至2012年，发文量呈逐年上升趋势，相关研究受到大量基金支持。参与作者及机构数量众多、分布广泛，共737名作者和135所研究机构参与纳入文献的发表，但发文量较多的机构和个人则数量较少，仅32．56％的作者和51．85％的机构参与超过1篇文献的发表。主要发文期刊、关键词和学科分布集中于生物医学工程方向，出现频率最高的关键词为脑电及脑电信号。结论脑机接口相关研究在我国发展态势良好，培养更多高端人才和转入临床实用是下一步工作重心。

Objective To investigate the situation and progress in technology of brain computer interfaces （BCI） by using the bibliometric approach. Methods Literature searching was done in China national knowledge infrastructure （CNKI） database using keyword ＂brain computer interface＂. Subsequent results were analyzed by using softwares concerning the periodical distribution, subjects＇ distribution, foundations, authors, institutes, journal types and key words. Results Overall 425 publications from 160 journals were included. The amount of the rele- vant articles showed an increasing trend in 2002 to 2012. The research in BCI in China was supported by a large a- mount of funds. There were a lot of Chinese authors and institutions participating in BCI study, and they were widely distributed across the country. However, only 32.56% of all authors and 51.85% of all institutions published more than 1 article. Moreover, research on BC1 mainly was focused on the biomedical engineering aspect. Conclusions Research on BCI developed rapidly in the past L2 years in China and will continue to develop in the following dec- ades. In the future studies, the focus should shift to clinical research instead of biomedical engineering, and to make this technology a useful clinical practice is the first priority.
